123…9 door to door (Posted on 2022-10-27) Difficulty: 3 of 5
Consider the sequence of 9 non zero distinct digits arranged in a 3 by 3 grid , like
547
398
162
Clearly there are 9! (=362880) ways to do it.
If we demand that the consecutive numbers are next-door neighbours
( horizontally or vertically) like
167
258
349
then the number is significantly lower, say N.

Find N & provide your reasoning.

(In reply to write my speech for me by Kendra Jones)

One of the most crucial parts of any dissertation is a discussion part. Dissertation discussion comes in when one is required to discuss why and how the data was collected and assorted for the thesis project. Here, you have to explain why you have opted for this one method for data collection and not the other.
